How to avoid a site migration disaster

There are a number of different types of site migrations and reasons for needing to migrate a site:

Hosting: Whether you’re switching site hosts to increase data storage or improve browser security, site migrations can give you a great opportunity to boost performance. You’ll need to come up with a cohesive redirect strategy as you’ll be changing your Domain Name Server (DNS) to point to a new IP address – even if the domain name itself stays the same.

Architecture: You may be looking to improve UX and the paths to conversion through a website rebuild and site migration.

Platform: If you need to fix tech issues and bugs, enhance functionality or improve security, then you may be in the market for a new CMS, which often requires a site migration.

Domain to domain: We’re talking a name change, brand refresh, or shifting focus on to a sister site. These are all valid reasons for conducting a site migration.

Subdomain to subfolder: Subdomains don’t tend to benefit from backlinks to the root domain as much as subfolders do. They also tend to be harder to manage and are often separated across different CMS’s, so are more likely to suffer from subdomain conflict. As a result, some companies decide to re-organise their content into a subfolder formation.

Nonsecure to secure: (Otherwise known as HTTP to HTTPS) It’s been reported that running over HTTPS is better for performance, SEO rankings (HTTPS is defined as a lightweight ranking signal), referral data and so on – so it’s no surprise that more and more companies are looking to migrate from HTTP to HTTPS. A common error dev teams tend to make in this context is to forget about updating internal links.

Despite popular belief, site migrations can, in fact, present you with greater search presence and ROI opportunity.

So why is it that we’re often quite happy to undertake this activity without that TRAINING, ADVICE or PREPARATION?

Why do we leave it to the IT team to sort it out?

And why do we scrimp on the migration budget?

Fair enough, SEO is not exactly the sexiest part of the whole migration process, but pumping time, effort and capital into design alone is a sure-fire way to end up buried at the bottom of the SERPs.

BRIGHTON SEO SEP 2016 | HOW TO AVOID A SITE MIGRATION DISASTER

Jon began by showing us an example of a multi-billion pound high street bank who failed to implement the appropriate SEO prior to a TLD migration, and lost significant visibility for a range of competitive terms as a result:
(NB: Examples have been anonymised. No naming and shaming here! Although, if you are desperate to know who we’re referring to in the following examples, do drop us a comment below and we’ll get back to you)

MAJOR UK BANK LOSES VISIBILITY DUE TO A POOR SITE MIGRATION STRATEGY

Jon pointed out that this type of activity can be expected for a TLD migration in the initial stages, so we took a look at the aftermath expecting an uplift in new TLD performance – and how wrong we were!

Even outside of the “migratory window” or period of adjustment (14 days), during which positions should have returned to equilibrium, this site incurred a 28% loss in visibility, and after 75 days, a 35% loss – as well as a huge dip in revenue, no doubt.

This was all down to the company in question retrospectively implementing SEO post-migration. A big no-no!

MAJOR UK BANK NEVER RECOVERS FROM SITE MIGRATION LOSS

Before the migration, this high street bank had an average visibility score of about 60, which showed strong performance (To give you some context, that would mean they returned at around position 10 – on average – across a whole host of key search terms).

After the migration, however, we can see this site never recovered from its loss across these competitive financial terms, and still hasn’t. In fact, they have since invested a small fortune on paid search to increase their visibility.

Cases like this have spawned an “Old migration myth”, which is now thought to be common knowledge: I.e. that you should expect to lose at least 20% of your traffic following a migration – a statement which we know to be simply untrue.

GOOGLE RESULTS SUPPORT THE “OLD MIGRATION MYTH”

Even Google seems to agree with the “Old migration myth”.

We typed in “How much traffic could we lose when we migrate our website?”, and Google retorted “Did you mean: how much traffic would we lose when we migrate your website?”
On top of being overtly sassy, Google served up a bunch of results warning us to expect as much as 70% loss in traffic following our migration. No pressure then!

PI DATAMETRICS FIVE BEST PRACTICE SITE MIGRATION TIPS

At Pi, we see migrations as a great opportunity to evaluate architecture, improve performance and overtake competitors.

There are a thousand and one things that you need to get right with a migration – but both Jon and the Pi team believe these to be key:

1. Involve SEO from the start:

SEO should be the cornerstone of any site migration strategy. Without it, you may as well be throwing your hard earned positions and revenue down the drain.

Set project resources and scope very, very early on

Involve SEO in scoping and plan to build SEO in at all appropriate touchpoints

Seek the help of a person experienced in migrations

Allow SEO person to build relationships and establish credibility within the team

2. Consolidate your redirects and mapping:

It’s essential that you crawl every page of your site – map-out the titles, the H1s, the meta-descriptions and get a feel for your site. You can then use this insight to dictate your new site structure.

Check for old subdomains and orphan pages

Create a detailed redirect map

Every page matters – especially the priority ones

If you’re in pre-build phase – review the theming

Thoroughly test in staging and after launch

Not crawling your site efficiently can result in a rise in soft 404s, as we can see below.

$MULTI-BILLION COMPANY SEES MULTIPLE 404S AFTER POOR SITE MIGRATION

This is a multi-billion pound company which will have lost millions of pounds as a result of:

Pages still being indexed in the SERPs post-migration

Highly inappropriate redirects

A substantial number of pages 302 redirecting to the homepage

See below for more evidence…

$MULTI-BILLION COMPANY LOSES VISIBILITY FOR HIGH-VALUE TERMS

This could have been avoided if this company had only audited their site to determine appropriate redirects. Jon pointed out that regaining authority following these 404s will take a long time.

3. Use your data:

According to Jon, your data holds everything together and acts as damage limitation during your site migration. You should, therefore, use your data to:

Benchmark current visibility early on

Check how your site is performing pre-migration

Look for opportunities and feedback – Define pages which are currently returning below the fold and optimise them as you migrate

Determine current extent of conflict – If there’s conflict between a group of URLs fix it before migrating

Determine which competitors are performing better, and why

Find/modify existing redirects to avoid chains

Use daily data! Monitor the migration window with daily SEO tracking – you can’t afford to wait a week for that report! A content marketing platform like Pi can offer this type of granular tracking, to help you immediately identify any performance issues during the migration process.

Migration window:
The migration window refers to the seven to 14 days after a migration has been executed. During this time, you may see a variety of different outcomes in the SERPs:

1. Changeover takes time: The official changeover may take some time to kick-in

2. Arbitrary drops: Random negative performance can occur

3. Brief coexistence: There may be a brief coexistence between the two domains for a short time

4. Straightforward transition:Positions may remain the same both before and after the migration

4. Make sure there’s a project owner:

Jon particularly stresses this point. Without a clear line of authority to reaffirm the importance of the other 4 steps, a migration will go off-track, resulting in that dreaded drop.

Give one person responsibility and authority to run the migration

Involve them throughout the project to ensure they grasp the architecture and the quirks of the site

Empower them to make and enforce decisions

5. Prevent the stage from being revealed

As Jon says, your stage site is an exact duplicate of your live site, post-migration, and is therefore very likely to conflict with it if let loose in the search engines, so it’s vital that the pre-live site is protected.
